@Carlo-Lancia You've demonstrated in the other thread that you know how to make a curl call with cookies. What I mean to say in my last reply is that the IFrame itself needs to pass that cookie to NodeBB so that the user sees the logged-in site. I don't know how to do that (I'm not an app developer).

Hi Julian, I just modified the file "src/controllers/write/users.js", as you indicated. Now I can generate the token. Ok! Grazie
